5. PARAMETERS
Class No. Symbol
23 FFC
Feed forward gain
Set the feed forward gain. When the setting is 100%, the droop pulses
during operation at constant speed are nearly zero. However, sudden
acceleration/deceleration will increase the overshoot. As a guideline,
when the feed forward gain setting is 100%, set 1s or more as the
acceleration/deceleration time constant up to the rated speed.
24 ZSP Zero speed
Used to set the output range of the zero speed (ZSP).
25 VCM Analog speed command maximum speed
Used to set the speed at the maximum input voltage (10V) of the
analog speed command (VC).
Set "0" to select the rated speed of the servo motor connected.
Analog speed limit maximum speed
Used to set the speed at the maximum input voltage (10V) of the
analog speed limit (VLA).
Set "0" to select the rated speed of the servo motor connected.
26 TLC Analog torque command maximum output
Used to set the output torque at the analog torque command voltage
(TC
100[%]. For example, set 50 to output (maximum torque
the TC of 8V.
27 *ENR Encoder output pulses
Used to set the encoder pulses (A-phase, B-phase) output by the
servo amplifier.
Set the value 4 times greater than the A-phase or B-phase pulses.
You can use parameter No. 54 to choose the output pulse setting or
output division ratio setting.
The number of A/B-phase pulses actually output is 1/4 times greater
than the preset number of pulses.
The maximum output frequency is 1.3Mpps (after multiplication by
4). Use this parameter within this range.
For output pulse designation
Set " 0
Set the number of pulses per servo motor revolution.
Output pulse
At the setting of 5600, for example, the actually output A/B-phase
pulses are as indicated below:
A B-phase output pulses
For output division ratio setting
Set " 1
The number of pulses per servo motor revolution is divided by the
set value.
Output pulse
At the setting of 8, for example, the actually output A/B-phase
pulses are as indicated below:
15
28 TL1 Internal torque limit 1
Set this parameter to limit servo motor torque on the assumption
that the maximum torque is 100[%].
When 0 is set, torque is not produced.
(Note)
Note. 0: off
When torque is output in analog monitor output, this set value is the
maximum output voltage ( 8V). (Refer to Section 3.4.1, (5))
